Slots that Let You Buy the Bonus Round

Bonus buy slots allow players to essentially purchase bonus rounds in the game. This is a relatively newer feature being added to online slot games driven by high player demand.

But, what slot games have this feature? And, where can you find them? 

What are Bonus Buy Slots? 

As an additional benefit, all of the slots have bonus buy slots that you may use to purchase games with a premium in return for a bonus feature. Most of the time, this is the round when you get free spins.

NextGen and Big Time Gaming are currently the biggest providers of bonus buy slots for online casinos in the United States. 


NextGen is one of the largest online slots providers in the world. You can find their games at most online casinos across the United States. 

Their most popular bonus buy slots at US online casinos include:

Big Time Gaming

Big Time Gaming, or BTG, was the first provider in the industry to offer online slots with a bonus buy feature. BTG is known for their Megaways slots, so it’s no surprise to see them applying the bonus buy feature to these slots.

How does the bonus buy feature work? 

To enter the bonus round in normal circumstances, you must land three or more scatter symbols on the reels.

You pay a premium to ensure that you reach the bonus game on the next spin if you choose the bonus buy option.

The bonus purchase feature can be extremely useful! After all, the bonus round is normally the part of the game with the most lucrative prizes.

Are Bonus Buy Slots Worth It?

Yes, they can be; bonus buys are used in slot games for a reason…or perhaps many reasons. The most significant advantages of this choice are mentioned below.

There is no need to wait for the bonus.

Again, you’ll have to wait several minutes or more to get the feature. Before you can play the bonus, you usually need three scatter symbols to appear anywhere on the screen.

Perhaps you like the base game and are willing to wait. You may be itching to play the feature but not in the mood to spin the reels for several minutes.

You have three options at this point:

1. Continue to spin the reels manually.

Switch on autoplay and return when the bonus has been activated.
Get the incentive by purchasing it.

There’s nothing wrong with manually spinning the reels or using autoplay. However, when you’re only trying to enjoy the bonus round, these routes can seem unnecessary.

When purchasing the function, you can skip all of the steps in between. You choose the bonus purchase option, pay the fee, and wait for the requisite triggering scatters to appear on the next spin.

2. Pursue the Most Lucrative Prizes

Some slots have a progressive jackpot that pays out the most money. However, many modern games associate the function with the highest payout.

E.g., the base game can only allow you to win 1,000 times your stake. However, the bonus allows you to play for a maximum of 20,000x.

Here’s an example of how this scenario could work in your favor:

  1. A game has a top reward of 20,000 times your bet.
  2. You place a $1 wager per spin.
  3. To trigger the feature, you must wager 75 times your bet ($75).
  4. You win the top prize of $20,000 and take it home.

Most slots have maximum prizes ranging from 5,000 to 50,000 times your bet. To get such a payout, you must, once again, be playing the feature.

3. Take advantage of the bonus.

You probably don’t start playing an online slot just for the bonus feature. You’re more than likely drawn in by the style, visuals, animations, and music.

But eventually, you’ll be itching to get the bonus. Expanding wilds, multipliers, random wilds, and other modifiers are among the action-packed features.

Purchasing a function means that you can use it whenever you want. This opportunity isn’t cheap, with payouts ranging from 50x to 100x your stake.

When deciding whether or not to activate it, you must exercise caution. Bonus buy, on the other hand, adds a lot to the game.

Buying a bonus round – Pros and Cons

Feature buy is a new betting choice that has only recently become available in online slots. It’s also known as a bonus buy because it helps you to access the bonus round right away.

This choice is appealing because it allows you to play the bonus at any time. Furthermore, it allows you to chase big prizes whenever you want.

Bonus buy, on the other hand, isn’t flawless and has certain drawbacks. As a result, I’ll go over feature buy in greater detail, as well as its benefits and drawbacks.

No money wasted on spins that award no winningsExpensive to buy pass

Tips on How to Use the Bonus Buy Round

It’s wise to conduct background research before purchasing the final bonus round.

1. Before you purchase

The thing is, buying a bonus seems to be the same for most games. There are a few things to remember.

Megaways slots frequently have the feature buy.

One of the advantages is that you normally get a higher RTP if you want to activate the bonus buy option. In comparison to normal gameplay, this ensures you have a better chance of winning.

2. Playing in a demo is helpful

This allows one to appreciate the payouts and free spins, and other mechanics of a slot game before paying for them.

You’ll be able to tell whether you should buy, hoping for a big prize or lose the bonus points, but you’ll need to make the decision based on the extent of your winnings.

3. Plan your budget

Make better use of your money if you have the flexibility to use a budget that matches your spending desires.

Because of this, it is best to put limits on your account for these games to make sure you are not exceeding your own funding limits. For more information on responsible gambling visit our page here.

What are Feature Buy Slots?

Instead of buying into the Bonus, some slot games allow you to pay for an extra feature or a better chance of triggering a feature.

This feature does not guarantee that you will be able to join a bonus, but it can help you do so (for example, by adding an extra scatter to the reels).

An Ante-bet option, also known as a Big Bet feature, is available in some games.

US players also have a better chance of triggering the bonus round if they play for a higher stake.

Other games encourage you to gamble the bonus round for the chance to win more free spins or to purchase an upgrade once the bonus round has been triggered.

These features are legal for US players as long as the bonus round is not guaranteed, and there are some slots that offer them.

What Features can you buy?

One of the advantages is that if you want to activate the bonus buy option, you will normally receive a higher RTP. When compared to standard gameplay, this ensures you have a better chance of winning.

Some games stand out more than others when it comes to the feature buy option.

Features on games enable you to wager the bonus round for the opportunity to win extra free spins or to purchase an upgrade once the bonus round has been triggered.

Only a few of our top-rated casinos provide the majority (if not all) of the feature-buy slots in their casino game lobby. To meet your bonus requirements, we recommend playing at one or more of the following casinos:

A few games we recommend which have all the features to buy.

Which is better: Bonus buy or Feature Buy?

A bonus buy option has one advantage: it ensures your participation in the bonus round.
The features buy option is worth a shot if you’re willing to pay a premium for instant action and access to what might turn out to be a lucrative bonus round.

You’re saving yourself hundreds, if not thousands, of spins of time and effort spent looking for bonus rounds. 

The feature purchase can be risky (in fact, some slots refer to it as a “gamble feature” for this reason). However, if you use it sparingly, it will save you money compared to using the full incentive purchase.

Are Bonus Buy Slots Legal in the US?

Yes, indeed. Playing real-money bonus buy slots in the United States is therefore legal unless your state forbids it. Since each state has its own set of gambling rules, the legality of online slots in the United States varies depending on where you live.

Customers from the United States earn the same welcome and reload promotions as players from other nations (although naturally US players only receive bonuses from casinos that allow US citizens to play slots for real money).

Great alternatives to Bonus Buy Slots?

You may want to look at some slots with great bonus features in addition to the feature buy slots we looked at above.

Online slots are available in a wide range of shapes and sizes, and they’re common all over the world. Of course, this is just a preference for the shape. If you want to try your hand at bonus buy slots, learn how to play the regular slot machine first.

Typical 5-Reel Slots

Basic 3-reel slots have undergone several improvements as the online gaming industry has evolved. Two extra reels were easily attached to their online versions.

As a result, there were more possible combinations, more opportunities to win, and therefore more gaming fun. You can quickly hit the payout target while playing 5-reel slots.

All you have to do is match a group of identical symbols from different reels on the same pay line.

Megaways Slots 

This sort of online slot is for those who enjoy doing micro calculations and putting their luck to the test. The central theory, in fact, is very straightforward.

Classic 5-reel slots typically have three rows on each reel. Simply multiply the number of reels with each other to determine the winning probability.

There are 243 pay lines in the ‘classic’ version. Megaways slots, on the other hand, have up to eight symbols on each reel. You can also come across 6-reel mega ways on occasion.

More than 200.000 pay lines are available as a result of this. Find more information about Megaway Slots here
